• The Grind
  • Before being extracted into the perfect shot of espresso, our expertly selected and roasted beans must be ground. “Milling” is one of the most critical steps in espresso-making and is best done as close in time to brewing as possible, as it releases many delicate aromatic compounds and increases the surface area so dramatically it opens the coffee to rapid oxidation and staling. To create the best Chiasso beverages possible, the beans are used immediately after grinding.

    The size of the grind particles is also important. The finer the grind, the more contact there is between the beans and the hot water, and the faster and more thoroughly the essential oils are released. Attention must paid so that harsher, less-soluble chemicals are not activated by too fine a grind, as the coffee will be destroyed by over-extraction. Too coarse a grind and the coffee may never develop its full flavor potential in the cup. Coffee beans are brittle and shatter as they are ground, so it’s never possible to get a uniform particle size. The trick is to get the average particle size perfect. Chiasso baristas adjust their grinders up to 30 times an hour, depending on temperature, humidity, and other environmental conditions, to keep the grind at the sweet spot as the beans age.
